Definitions

  • This invention relates to an apparatus for detecting whether a cotton or chemical fiber sliver in a fiber processing machine, particularly a draw frame, is advanced or is stationary and/or whether it is present or absent.
  • the sliver passes through a space accommodating at least one sensor device composed of a transmitter and a receiver.
  • the direction of sensor rays (such as light rays) is essentially perpendicular to the advancing direction of the sliver.
  • the thickness of the sliver is consecutively measured by a sensor device and, by comparing the data with at least one previous measurement, it is determined whether changes in the thickness occur as a function of time. A difference in the thickness measured indicates that the sliver moves. It is a disadvantage of such an arrangement that the sensor device is structurally expensive. In particular, the receiving device for detecting the sliver thickness (shadow effect) is complex.
  • a fiber processing machine includes an arrangement for forwarding a sliver through a space in an advancing direction; an arrangement for continuously displacing the sliver in the space transversely to the advancing direction while the sliver is forwarded in the advancing direction; and an apparatus for detecting a presence, absence, motion or standstill of a sliver.
  • the apparatus includes a transmitter emitting a sensor beam passing through the space transversely to advancing direction for being intermittently interrupted by the sliver during displacement thereof transversely to the advancing direction; and a receiver positioned in a path of the sensor beam for receiving a light or a dark signal dependent whether or not the sensor beam is interrupted by the sliver during displacement thereof transversely to the advancing direction.
  • a sliver motion in the advancing direction may be detected in a simple manner by virtue of the fact that the sliver is movable along a path lying in a plane which is essentially perpendicular to the advancing direction.
  • the sliver periodically intersects (interrupts) the sensor rays, it is an indication that the sliver moves in the advancing direction.
  • the rays are continuously either interrupted or not interrupted, it is an indication that the sliver is either stationary or no sliver is present (that is, a sliver rupture has occurred).
  • the path of the sliver may be circular or oval.
  • the space where measurement takes place is the inner space of a sliver guide.
  • optical or electro-optical transmitter and receiver elements are integrated in the sliver guide.
  • the inner space of the sliver guide has a circular outline.
  • the sliver guide is situated at the creel of a draw frame, between a coiler can and a deflecting roll (supply roll) mounted on the creel.
  • the transmitter and the receiver are situated in the sliver guide and a transmitter part and a receiver part are flush with the inner wall defining the inner space of the sliver guide.
  • a ray-deflecting mirror (reflector) is provided.
  • the transmitter and the receiver are connected to an electronic microcomputer control-and-regulating device (computer) and the signals produced by the receiver are processed by an electronic evaluating device.
  • a microcomputer control-and-regulating device computer
  • the fiber processing machine simultaneously handles a plurality of slivers, each passing through its own sliver guide and with each sliver guide a separate sensor apparatus is associated.
  • the invention further encompasses an apparatus for detecting textile fibers in fiber processing machines, particularly draw frames, where, one or more electrooptical transmitters, receivers and/or reflector (mirror) combinations are provided for each sliver to be sensed. Each such combination is preferably integrated into a respective sliver guide.
  • the signals of the receivers are centrally processed by an evaluating unit which is connected to the usual machine control system, and, for an optimal detection, obtains information on the condition of the fiber processing machine and transfers information on all the incoming slivers to the machine control system.
  • a central evaluating unit is provided which is connected with the usual machine control.
  • the evaluating unit may utilize information on the momentary operating parameters of the draw frame such as output speed.
  • the detection system operates in a “self-learning” mode in which the signal pattern used for comparison during a learning phase or during certain occurrences is saved. Since the sliver in practice often does not move on an ideal circular path and the shape of the actual displacement depends, among others, from the material used, the output rate as well as the sliver thickness, the material-specific and production-specific behavior of the sliver may be detected once or continuously by self-learning. Thereafter the results may be repeatedly compared with the production in progress and in case of significant deviations, a suitable response (for example, braking) is triggered. Thus, in this manner material-specific and production-specific signal patterns of the receiver may be generated and stored and may be called later if needed for comparison. Such a function is particularly advantageous for a plurality of sensor units when a central evaluating unit is used.
  • the detected signal patterns are automatically or manually adjusted as a function of production conditions. Given such a possibility, the detected signal pattern may be adjusted, for example, as a function of changes in the production speed and to thus again obtain an operationally reliable detection.
  • the utilized signal patterns are adjusted or corrected as a function of certain production parameters of the fiber processing machine.
  • the electrooptical transmitter and receiver elements are not situated in the detection unit but at another location, preferably on the evaluating unit and transfer the optical information by means of optical wave guides from the detection unit to the transmitter and receiver elements. This provides for a further advantageous possibility to economically build the detection units having a small spatial requirement.
  • the motion of the sliver is detected by comparing the generated signal pattern emitted by the receiver with a previously inputted pattern.
  • the evaluation of the receiver signals is carried out while taking certain production parameters into consideration.
  • the fiber processing machine is controlled as a function of the evaluated signals.
  • the evaluating unit transfers separate signals for “sliver is present” and “sliver is in motion” to the machine control system.
  • the evaluating unit transfers in each instance a joint signal to the machine control for all the receivers.
  • the braking of the fiber processing machine occurs when a sliver is missing or is stationary, dependent on the position of the sliver. Since such a braking has to occur very rapidly (substantial deceleration), the moving components (for example, drive belts of the machine) are highly stressed. It is therefore desired that such a braking not be more forceful than absolutely necessary to thus only ensure that the remainder of a broken sliver does not enter into the measuring intake trumpet.
  • the intake locations of the slivers may be several meters apart, in case of a failure of an incoming sliver which enters the machine at a substantial distance from the measuring intake trumpet, the machine may be braked less forcefully and thus the material is more gently handled than in case of a sliver which enters very close to the trumpet.
  • the evaluating unit apart from determining “sliver present/not present” and “sliver moves/doesn't move”, may transmit further information to the engine control system, for example, for the purpose of plausibility checks.

  • FIG. 2 shows an embodiment with four supply rolls 8 a - 8 d and eight upper rolls 9 a - 9 h .
  • each supply roll is provided with two upper rolls serving sliver from the one and the other coiler can row.
  • the supply rolls may have the same diameter, for example, 100 mm, and they may be driven such that their rpm, and thus their circumferential speed decrease in the working direction A.
  • the supply rolls may be driven by individual motors, or by a single motor via gearing or step-down devices.
  • the slivers 7 a - 7 h run from respective sliver guides 10 a - 10 h (each including a measuring unit) essentially linearly and parallel to one another. Such a sliver orientation may be maintained up to the end of the draw unit 3 .
  • the sliver 7 a pulled from the coiler can 5 a first rises from the coiler can 5 a as a sliver portion 7 ′ and then passes through the opening (eyelet) of the sliver guide 10 a and, while doing so, is deflected in the direction A and subsequently enters through the nip between the driven supply roll 8 a and the co-rotating upper roll 9 a .

  • the sliver guide 10 a is, by means of a holding bar 19 and a securing ring 20 , attached to a stationary holding bar 18 which, in turn, is mounted on the creel 6 .
  • the sliver 7 is deposited in loops in the coiler can 5 e such that the loops do not reach the can center. This is frequently the case when large coiler cans (moved from the non-illustrated carding machine) are used.

  • the top plan view of FIG. 3 a shows that the sliver 7 is deposited in loops in the coiler can 5 .

  • the angular position of the sliver guide 10 related to the securing ring 20 may also be changed by rotating the sliver guide 10 , together with the holding bar 19 in the direction E, whereby different magnitudes and/or positions of the coiler cans with respect to the location of the sliver guide 10 may be taken into account.
  • FIG. 4 b shows an essentially horizontal position of the sliver guide 10 which is an expedient orientation in practice.
  • the apparatus according to the invention can monitor whether all the slivers 7 a - 7 h (thus, usually up to eight in number) which should enter the textile machine, particularly a draw frame, are in fact present. Further, it is not only recognized whether the slivers are present or absent but also whether they move or are at a standstill. In some cases it may occur that while a particular sliver is present, it has ruptured and thus does not enter the machine for further processing.
  • the detection of each sliver occurs in the region of the creel 6 , in the zone of the location of deflection, where the sliver is essentially vertically pulled from the respective coiler can and is brought by a respective sliver guiding and deflecting elements into a horizontal position.

  • a momentary position of the sliver is shown in phantom lines and is designated at 7 a ′. In that momentary position the upward advancing direction is designated at B′.

  • the running sliver moves essentially perpendicularly to the longitudinal advancing direction (which is perpendicular to the plane of FIG. 5 b ), that is, perpendicularly to the non-illustrated virtual axis of the balloon.
  • the direction of the path H follows the direction of removal of the loops deposited in the coiler can 5 .
  • the detection occurs by electro-optical assemblies composed of one or several transmitter/receiver and/or reflector combinations.
